Educational objectives Learning outcome
The course aims to introduce the theoretical and computational aspects for the solution of problems in which the mechanical aspects (elasticity, plasticity, etc.) are coupled with different physics (thermal, diffusion, growth, ...) in order to evaluate and optimize the mechanical performanceof devices such as batteries, solar panels, pneumatics,...
At the end of the course the student will be able to: c understand and assimilate the fundamentals of solid mechanics, identifying the most important aspects of material modeling, such as the dissipation mechanisms associated with nonlinear behavior; chonor the theoretical and practical foundations of the finite element method for the analysis of structures subjected to dynamic and static loads; to take the fundamentals of the thermodynamics of solid continuums and the theory of diffusion growth; to understand the most important aspects of the spatial and temporal discretization of the problems addressed.
Course Structure
The course is divided into two parts. In the first, the numerical methods applied to the modeling of the behavior of nonlinear materials will be illustrated, with particular emphasis on the integration of constitutive models and generalizations of the finite element method for nonlinear problems. The fundamentals of solid mechanics under finite deformations will be illustrated, identifying the most important aspects of material modeling, such as the dissipation mechanisms associated with visco-elastic and visco-plastic behavior. At the end of the first part the student will be able to understand and assimilate the fundamentals of non-linear finite element analysis, obtain the weak form of the variational formulation and its solution, as well as know the basic structure of a finite element program.
In the second part, various computational approaches for the numerical simulation of coupled problems will be presented and discussed. First, we will study thermo-mechanical and electro-mechanical problems, analyzing the different potential sources of coupling, as well as their implications from a computational point of view. The different algorithms will then be put into practice in project work for various problems (thermoplasticity, thermo-visco-elasticity, piezo-electricity, etc.). Secondly, the focus will be placed on chemo-mechanical problems where the coupling is between elasticity, plasticity and the diffusion of chemical species (ions) within the material. Lithium-ion batteries will be considered as an application where the diffusion of lithium in the anode can cause volume variations and high states of stress such as to impair the operation of the device.
